BACKGROUND OF THE INVENTION

The present invention relates to a new and distinctive soybean cultivar,designated S080122. All publications cited in this application areherein incorporated by reference.

There are numerous steps in the development of any novel, desirableplant germplasm. Plant breeding begins with the analysis and definitionof problems and weaknesses of the current germplasm, the establishmentof program goals, and the definition of specific breeding objectives.The next step is selection of germplasm that possesses the traits tomeet the program goals. The goal is to combine in a single variety animproved combination of desirable traits from the parental germplasm.These important traits may include higher seed yield, resistance todiseases and insects, better stems and roots, tolerance to drought andheat, and better agronomic quality.

Choice of breeding or selection methods depends on the mode of plantreproduction, the heritability of the trait(s) being improved, and thetype of cultivar used commercially (e.g., F₁ hybrid cultivar, purelinecultivar, etc.). For highly heritable traits, a choice of superiorindividual plants evaluated at a single location will be effective,whereas for traits with low heritability, selection should be based onmean values obtained from replicated evaluations of families of relatedplants. Popular selection methods commonly include pedigree selection,modified pedigree selection, mass selection, and recurrent selection.

The complexity of inheritance influences choice of the breeding method.Backcross breeding is used to transfer one or a few favorable genes fora highly heritable trait into a desirable cultivar. This approach hasbeen used extensively for breeding disease-resistant cultivars. Variousrecurrent selection techniques are used to improve quantitativelyinherited traits controlled by numerous genes. The use of recurrentselection in self-pollinating crops depends on the ease of pollination,the frequency of successful hybrids from each pollination and the numberof hybrid offspring from each successful cross.

Each breeding program should include a periodic, objective evaluation ofthe efficiency of the breeding procedure. Evaluation criteria varydepending on the goal and objectives, but should include gain fromselection per year based on comparisons to an appropriate standard,overall value of the advanced breeding lines, and number of successfulcultivars produced per unit of input (e.g., per year, per dollarexpended, etc.).

Promising advanced breeding lines are thoroughly tested and compared toappropriate standards in environments representative of the commercialtarget area(s) for three or more years. The best lines are candidatesfor new commercial cultivars; those still deficient in a few traits maybe used as parents to produce new populations for further selection.

These processes, which lead to the final step of marketing anddistribution, usually take from eight to twelve years from the time thefirst cross is made. Therefore, development of new cultivars is atime-consuming process that requires precise forward planning, efficientuse of resources, and a minimum of changes in direction.

A most difficult task is the identification of individuals that aregenetically superior, because for most traits the true genotypic valueis masked by other confounding plant traits or environmental factors.One method of identifying a superior plant is to observe its performancerelative to other experimental plants and to a widely grown standardcultivar. If a single observation is inconclusive, replicatedobservations provide a better estimate of its genetic worth.

The goal of soybean plant breeding is to develop new, unique andsuperior soybean cultivars and hybrids. The breeder initially selectsand crosses two or more parental lines, followed by repeated selfing andselection, producing many new genetic combinations. The breeder cantheoretically generate billions of different genetic combinations viacrossing, selection, selfing and mutations. Therefore, a breeder willnever develop the same line, or even very similar lines, having the samesoybean traits from the exact same parents.

Each year, the plant breeder selects the germplasm to advance to thenext generation. This germplasm is grown under unique and differentgeographical, climatic and soil conditions and further selections arethen made during and at the end of the growing season. The cultivarsthat are developed are unpredictable because the breeder's selectionoccurs in unique environments with no control at the DNA level, and withmillions of different possible genetic combinations being generated. Abreeder of ordinary skill in the art cannot predict the final resultinglines he develops, except possibly in a very gross and general fashion.The same breeder cannot produce the same cultivar twice by using thesame original parents and the same selection techniques. Thisunpredictability results in the expenditure of large amounts of researchmonies to develop superior new soybean cultivars.

The development of new soybean cultivars requires the development andselection of soybean varieties, the crossing of these varieties andselection of superior hybrid crosses. The hybrid seed is produced bymanual crosses between selected male-fertile parents or by using malesterility systems. These hybrids are selected for certain single genetraits such as pod color, flower color, pubescence color or herbicideresistance which indicate that the seed is truly a hybrid. Additionaldata on parental lines, as well as the phenotype of the hybrid,influence the breeder's decision whether to continue with the specifichybrid cross.

Pedigree breeding and recurrent selection breeding methods are used todevelop cultivars from breeding populations. Breeding programs combinedesirable traits from two or more cultivars or various broad-basedsources into breeding pools from which cultivars are developed byselfing and selection of desired phenotypes. The new cultivars areevaluated to determine which have commercial potential.

Pedigree breeding is used commonly for the improvement ofself-pollinating crops. Two parents that possess favorable,complementary traits are crossed to produce an F₁. An F₂ population isproduced by selfing one or several F₁s. Selection of the bestindividuals may begin in the F₂ population; then, beginning in the F₃,the best individuals in the best families are selected. Replicatedtesting of families can begin in the F₄ generation to improve theeffectiveness of selection for traits with low heritability. At anadvanced stage of inbreeding (i.e., F₆ and F₇), the best lines ormixtures of phenotypically similar lines are tested for potentialrelease as new cultivars.

Mass and recurrent selections can be used to improve populations ofeither self- or cross-pollinating crops. A genetically variablepopulation of heterozygous individuals is either identified, or created,by intercrossing several different parents. The best plants are selectedbased on individual superiority, outstanding progeny, or excellentcombining ability. The selected plants are intercrossed to produce a newpopulation in which further cycles of selection are continued.

Backcross breeding has been used to transfer genes for a simplyinherited, highly heritable trait into a desirable homozygous cultivaror inbred line which is the recurrent parent. The source of the trait tobe transferred is called the donor parent. After the initial cross,individuals possessing the phenotype of the donor parent are selectedand repeatedly crossed (backcrossed) to the recurrent parent. Theresulting plant is expected to have the attributes of the recurrentparent (e.g., cultivar) and the desirable trait transferred from thedonor parent.

The single-seed descent procedure in the strict sense refers to plantinga segregating population, harvesting a sample of one seed per plant, andusing the one-seed sample to plant the next generation. When thepopulation has been advanced from the F₂ to the desired level ofinbreeding, the plants from which lines are derived will each trace todifferent F₂ individuals. The number of plants in a population declineseach generation due to failure of some seeds to germinate or some plantsto produce at least one seed. As a result, not all of the F₂ plantsoriginally sampled in the population will be represented by a progenywhen generation advance is completed.

In a multiple-seed procedure, soybean breeders commonly harvest one ormore pods from each plant in a population and thresh them together toform a bulk. Part of the bulk is used to plant the next generation andpart is put in reserve. The procedure has been referred to as modifiedsingle-seed descent or the pod-bulk technique.

The multiple-seed procedure has been used to save labor at harvest. Itis considerably faster to thresh pods with a machine than to remove oneseed from each by hand for the single-seed procedure. The multiple-seedprocedure also makes it possible to plant the same number of seeds of apopulation each generation of inbreeding. Enough seeds are harvested tomake up for those plants that did not germinate or produce seed.

In addition to phenotypic observations, the genotype of a plant can alsobe examined. There are many laboratory-based techniques available forthe analysis, comparison and characterization of plant genotype; amongthese are Isozyme Electrophoresis, Restriction Fragment LengthPolymorphisms (RFLPs), Randomly Amplified Polymorphic DNAs (RAPDs),Arbitrarily Primed Polymerase Chain Reaction (AP-PCR), DNA AmplificationFingerprinting (DAF), Sequence Characterized Amplified Regions (SCARs),Amplified Fragment Length polymorphisms (AFLPs), Simple Sequence Repeats(SSRs—which are also referred to as Microsatellites), and SingleNucleotide Polymorphisms (SNPs).

Proper testing should detect any major faults and establish the level ofsuperiority or improvement over current cultivars. In addition toshowing superior performance, there must be a demand for a new cultivarthat is compatible with industry standards or which creates a newmarket. The introduction of a new cultivar will incur additional coststo the seed producer, the grower, processor and consumer for specialadvertising and marketing, altered seed and commercial productionpractices, and new product utilization. The testing preceding release ofa new cultivar should take into consideration research and developmentcosts as well as technical superiority of the final cultivar. Forseed-propagated cultivars, it must be feasible to produce seed easilyand economically.

Soybean, Glycine max (L), is an important and valuable field crop. Thus,a continuing goal of soybean plant breeders is to develop stable, highyielding soybean cultivars that are agronomically sound. The reasons forthis goal are obviously to maximize the amount of grain produced on theland used and to supply food for both animals and humans. To accomplishthis goal, the soybean breeder must select and develop soybean plantsthat have traits that result in superior cultivars.

The foregoing examples of the related art and limitations relatedtherewith are intended to be illustrative and not exclusive. Otherlimitations of the related art will become apparent to those of skill inthe art upon a reading of the specification.

Further Embodiments of the Invention

The advent of new molecular biological techniques has allowed theisolation and characterization of genetic elements with specificfunctions, such as encoding specific protein products. Scientists in thefield of plant biology developed a strong interest in engineering thegenome of plants to contain and express foreign genetic elements, oradditional, or modified versions of native or endogenous geneticelements in order to alter the traits of a plant in a specific manner.Any DNA sequences, whether from a different species or from the samespecies, which are introduced into the genome using transformation orvarious breeding methods are referred to herein collectively as“transgenes.” In some embodiments of the invention, a transgenic variantof soybean cultivar S080122 may contain at least one transgene but couldcontain at least 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, and/or no more than 15,14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, or 2. Over the last fifteen totwenty years several methods for producing transgenic plants have beendeveloped, and the present invention also relates to transgenic variantsof the claimed soybean variety S080122.

Nucleic acids or polynucleotides refer to RNA or DNA that is linear orbranched, single or double stranded, or a hybrid thereof. The term alsoencompasses RNA/DNA hybrids. These terms also encompass untranslatedsequence located at both the 3′ and 5′ ends of the coding region of thegene: at least about 1000 nucleotides of sequence upstream from the 5′end of the coding region and at least about 200 nucleotides of sequencedownstream from the 3′ end of the coding region of the gene. Less commonbases, such as inosine, 5-methylcytosine, 6-methyladenine, hypoxanthineand others can also be used for antisense, dsRNA and ribozyme pairing.For example, polynucleotides that contain C-5 propyne analogues ofuridine and cytidine have been shown to bind RNA with high affinity andto be potent antisense inhibitors of gene expression. Othermodifications, such as modification to the phosphodiester backbone, orthe 2′-hydroxy in the ribose sugar group of the RNA can also be made.The antisense polynucleotides and ribozymes can consist entirely ofribonucleotides, or can contain mixed ribonucleotides anddeoxyribonucleotides. The polynucleotides of the invention may beproduced by any means, including genomic preparations, cDNApreparations, in vitro synthesis, RT-PCR, and in vitro or in vivotranscription.

One embodiment of the invention is a process for producing soybeanvariety S080122 further comprising a desired trait, said processcomprising introducing a transgene that confers a desired trait to asoybean plant of variety S080122. Another embodiment is the productproduced by this process. In one embodiment the desired trait may be oneor more of herbicide resistance, insect resistance, disease resistance,decreased phytate, or modified fatty acid or carbohydrate metabolism.The specific gene may be any known in the art or listed herein,including: a polynucleotide conferring resistance to imidazolinone,dicamba, sulfonylurea, glyphosate, glufosinate, triazine, benzonitrile,cyclohexanedione, phenoxy proprionic acid, and L-phosphinothricin; apolynucleotide encoding a Bacillus thuringiensis polypeptide; apolynucleotide encoding phytase, FAD-2, FAD-3, galactinol synthase, or araffinose synthetic enzyme; or a polynucleotide conferring resistance tosoybean cyst nematode, brown stem rot, Phytophthora root rot, soybeanmosaic virus, or sudden death syndrome.

Numerous methods for plant transformation have been developed, includingbiological and physical plant transformation protocols. See, forexample, Miki et al., “Procedures for Introducing Foreign DNA intoPlants,” in Methods in Plant Molecular Biology and Biotechnology, Glickand Thompson Eds., CRC Press, Inc., Boca Raton, pp. 67-88 (1993), andArmstrong, “The First Decade of Maize Transformation: A Review andFuture Perspective,” Maydica, 44:101-109 (1999). In addition, expressionvectors and in vitro culture methods for plant cell or tissuetransformation and regeneration of plants are available. See, forexample, Gruber, et al., “Vectors for Plant Transformation,” in Methodsin Plant Molecular Biology and Biotechnology, Glick and Thompson Eds.,CRC Press, Inc., Boca Raton, pp. 89-119 (1993).

A genetic trait which has been engineered into the genome of aparticular soybean plant may then be moved into the genome of anothervariety using traditional breeding techniques that are well known in theplant breeding arts. For example, a backcrossing approach is commonlyused to move a transgene from a transformed soybean variety into analready developed soybean variety, and the resulting backcrossconversion plant would then comprise the transgene(s).

Various genetic elements can be introduced into the plant genome usingtransformation. These elements include, but are not limited to, genes,coding sequences, inducible, constitutive and tissue specific promoters,enhancing sequences, and signal and targeting sequences. For example,see the traits, genes, and transformation methods listed in U.S. Pat.No. 6,118,055.

Plant transformation involves the construction of an expression vectorwhich will function in plant cells. Such a vector comprises DNAcomprising a gene under control of, or operatively linked to, aregulatory element (for example, a promoter). The expression vector maycontain one or more such operably linked gene/regulatory elementcombinations. The vector(s) may be in the form of a plasmid and can beused alone or in combination with other plasmids to provide transformedsoybean plants using transformation methods as described below toincorporate transgenes into the genetic material of the soybeanplant(s).

Expression Vectors for Soybean Transformation: Marker Genes

Expression vectors include at least one genetic marker operably linkedto a regulatory element (for example, a promoter) that allowstransformed cells containing the marker to be either recovered bynegative selection, i.e., inhibiting growth of cells that do not containthe selectable marker gene, or by positive selection, i.e., screeningfor the product encoded by the genetic marker. Many commonly usedselectable marker genes for plant transformation are well known in thetransformation arts, and include, for example, genes that code forenzymes that metabolically detoxify a selective chemical agent which maybe an antibiotic or an herbicide, or genes that encode an altered targetwhich is insensitive to the inhibitor. A few positive selection methodsare also known in the art.

One commonly used selectable marker gene for plant transformation is theneomycin phosphotransferase II (nptII) gene which, when under thecontrol of plant regulatory signals, confers resistance to kanamycin.Fraley, et al., Proc. Natl. Acad. Sci. USA, 80:4803 (1983). Anothercommonly used selectable marker gene is the hygromycinphosphotransferase gene which confers resistance to the antibiotichygromycin. Vanden Elzen, et al., Plant Mol. Biol., 5:299 (1985).

Additional selectable marker genes of bacterial origin that conferresistance to antibiotics include gentamycin acetyl transferase,streptomycin phosphotransferase and aminoglycoside-3′-adenyltransferase, the bleomycin resistance determinant (Hayford, et al.,Plant Physiol., 86:1216 (1988); Jones, et al., Mol. Gen. Genet., 210:86(1987); Svab, et al., Plant Mol. Biol., 14:197 (1990); Hille, et al.,Plant Mol. Biol., 7:171 (1986)). Other selectable marker genes conferresistance to herbicides such as glyphosate, glufosinate, or bromoxynil(Comai, et al., Nature, 317:741-744 (1985); Gordon-Kamm, et al., PlantCell, 2:603-618 (1990); Stalker, et al., Science, 242:419-423 (1988)).

Selectable marker genes for plant transformation not of bacterial origininclude, for example, mouse dihydrofolate reductase, plant5-enolpyruvylshikimate-3-phosphate synthase, and plant acetolactatesynthase (Eichholtz, et al., Somatic Cell Mol. Genet., 13:67 (1987);Shah, et al., Science, 233:478 (1986); Charest, et al., Plant Cell Rep.,8:643 (1990)).

Another class of marker genes for plant transformation requiresscreening of presumptively transformed plant cells, rather than directgenetic selection of transformed cells, for resistance to a toxicsubstance such as an antibiotic. These genes are particularly useful toquantify or visualize the spatial pattern of expression of a gene inspecific tissues and are frequently referred to as reporter genesbecause they can be fused to a gene or gene regulatory sequence for theinvestigation of gene expression. Commonly used genes for screeningpresumptively transformed cells include β-glucuronidase (GUS),β-galactosidase, luciferase, and chloramphenicol acetyltransferase(Jefferson, R. A., Plant Mol. Biol. Rep., 5:387 (1987); Teeri, et al.,EMBO J., 8:343 (1989); Koncz, et al., Proc. Natl. Acad. Sci. USA, 84:131(1987); DeBlock, et al., EMBO J., 3:1681 (1984)).

In vivo methods for visualizing GUS activity that do not requiredestruction of plant tissue are available (Molecular Probes, Publication2908, IMAGENE GREEN, pp. 1-4 (1993); Naleway, et al., J. Cell Biol.,115:151a (1991)). However, these in vivo methods for visualizing GUSactivity have not proven useful for recovery of transformed cellsbecause of low sensitivity, high fluorescent backgrounds, andlimitations associated with the use of luciferase genes as selectablemarkers.

More recently, a gene encoding Green Fluorescent Protein (GFP) has beenutilized as a marker for gene expression in prokaryotic and eukaryoticcells (Chalfie, et al., Science, 263:802 (1994)). GFP and mutants of GFPmay be used as screenable markers.

Expression Vectors for Soybean Transformation: Promoters

Genes included in expression vectors must be driven by a nucleotidesequence comprising a regulatory element (for example, a promoter).Several types of promoters are well known in the transformation arts asare other regulatory elements that can be used alone or in combinationwith promoters.

As used herein, “promoter” includes reference to a region of DNAupstream from the start of transcription and involved in recognition andbinding of RNA polymerase and other proteins to initiate transcription.A “plant promoter” is a promoter capable of initiating transcription inplant cells. Examples of promoters under developmental control includepromoters that preferentially initiate transcription in certain tissues,such as leaves, roots, seeds, fibers, xylem vessels, tracheids, orsclerenchyma. Such promoters are referred to as “tissue-preferred.”Promoters that initiate transcription only in a certain tissue arereferred to as “tissue-specific.” A “cell-type” specific promoterprimarily drives expression in certain cell types in one or more organs,for example, vascular cells in roots or leaves. An “inducible” promoteris a promoter which is under environmental control. Examples ofenvironmental conditions that may effect transcription by induciblepromoters include anaerobic conditions or the presence of light.Tissue-specific, tissue-preferred, cell-type specific, and induciblepromoters constitute the class of “non-constitutive” promoters. A“constitutive” promoter is a promoter that is active under mostenvironmental conditions.

A. Inducible Promoters—An inducible promoter is operably linked to agene for expression in soybean. Optionally, the inducible promoter isoperably linked to a nucleotide sequence encoding a signal sequencewhich is operably linked to a gene for expression in soybean. With aninducible promoter the rate of transcription increases in response to aninducing agent.

Any inducible promoter can be used in the instant invention. See, Ward,et al., Plant Mol. Biol., 22:361-366 (1993). Exemplary induciblepromoters include, but are not limited to, that from the ACEI systemwhich responds to copper (Mett, et al., Proc. Natl. Acad. Sci. USA,90:4567-4571 (1993)); In2 gene from maize which responds tobenzenesulfonamide herbicide safeners (Hershey, et al., Mol. GenGenetics, 227:229-237 (1991); Gatz, et al., Mol. Gen. Genetics,243:32-38 (1994)); or Tet repressor from Tn10 (Gatz, et al., Mol. Gen.Genetics, 227:229-237 (1991)). A particularly preferred induciblepromoter is a promoter that responds to an inducing agent to whichplants do not normally respond. An exemplary inducible promoter is theinducible promoter from a steroid hormone gene, the transcriptionalactivity of which is induced by a glucocorticosteroid hormone (Schena,et al., Proc. Natl. Acad. Sci. USA, 88:0421 (1991)).

B. Constitutive Promoters—A constitutive promoter is operably linked toa gene for expression in soybean or the constitutive promoter isoperably linked to a nucleotide sequence encoding a signal sequencewhich is operably linked to a gene for expression in soybean.

Many different constitutive promoters can be utilized in the instantinvention. Exemplary constitutive promoters include, but are not limitedto, the promoters from plant viruses such as the 35S promoter from CaMV(Odell, et al., Nature, 313:810-812 (1985)) and the promoters from suchgenes as rice actin (McElroy, et al., Plant Cell, 2: 163-171 (1990));ubiquitin (Christensen, et al., Plant Mol. Biol., 12:619-632 (1989);Christensen, et al., Plant Mol. Biol., 18:675-689 (1992)); pEMU (Last,et al., Theor. Appl. Genet., 81:581-588 (1991)); MAS (Velten, et al.,EMBO J., 3:2723-2730 (1984)); and maize H3 histone (Lepetit, et al.,Mol. Gen. Genetics, 231:276-285 (1992); Atanassova, et al., PlantJournal, 2 (3): 291-300 (1992)). The ALS promoter, Xbal/Ncol fragment 5′to the Brassica napus ALS3 structural gene (or a nucleotide sequencesimilarity to said Xbal/Ncol fragment), represents a particularly usefulconstitutive promoter. See, PCT Application WO 96/30530.

C. Tissue-Specific or Tissue-Preferred Promoters—A tissue-specificpromoter is operably linked to a gene for expression in soybean.Optionally, the tissue-specific promoter is operably linked to anucleotide sequence encoding a signal sequence which is operably linkedto a gene for expression in soybean. Plants transformed with a gene ofinterest operably linked to a tissue-specific promoter produce theprotein product of the transgene exclusively, or preferentially, in aspecific tissue.

Any tissue-specific or tissue-preferred promoter can be utilized in theinstant invention. Exemplary tissue-specific or tissue-preferredpromoters include, but are not limited to, a root-preferred promotersuch as that from the phaseolin gene (Murai, et al., Science, 23:476-482(1983); Sengupta-Gopalan, et al., Proc. Natl. Acad. Sci. USA,82:3320-3324 (1985)); a leaf-specific and light-induced promoter such asthat from cab or rubisco (Simpson, et al., EMBO J., 4(11):2723-2729(1985); Timko, et al., Nature, 318:579-582 (1985)); an anther-specificpromoter such as that from LAT52 (Twell, et al., Mol. Gen. Genetics,217:240-245 (1989)); a pollen-specific promoter such as that from Zm13(Guerrero, et al., Mol. Gen. Genetics, 244:161-168 (1993)); or amicrospore-preferred promoter such as that from apg (Twell, et al., Sex.Plant Reprod., 6:217-224 (1993)).

Signal Sequences for Targeting Proteins to Subcellular Compartments

Transport of a protein produced by transgenes to a subcellularcompartment, such as the chloroplast, vacuole, peroxisome, glyoxysome,cell wall, or mitochondrion, or for secretion into the apoplast, isaccomplished by means of operably linking the nucleotide sequenceencoding a signal sequence to the 5′ and/or 3′ region of a gene encodingthe protein of interest. Targeting sequences at the 5′ and/or 3′ end ofthe structural gene may determine during protein synthesis andprocessing where the encoded protein is ultimately compartmentalized.

The presence of a signal sequence directs a polypeptide to either anintracellular organelle or subcellular compartment or for secretion tothe apoplast. Many signal sequences are known in the art. See, forexample, Becker, et al., Plant Mol. Biol., 20:49 (1992); Knox, C., etal., Plant Mol. Biol., 9:3-17 (1987); Lerner, et al., Plant Physiol.,91:124-129 (1989); Frontes, et al., Plant Cell, 3:483-496 (1991);Matsuoka, et al., Proc. Natl. Acad. Sci., 88:834 (1991); Gould, et al.,J Cell. Biol., 108:1657 (1989); Creissen, et al., Plant J., 2:129(1991); Kalderon, et al., Cell, 39:499-509 (1984); Steifel, et al.,Plant Cell, 2:785-793 (1990).

Foreign Protein Genes and Agronomic Genes

With transgenic plants according to the present invention, a foreignprotein can be produced in commercial quantities. Thus, techniques forthe selection and propagation of transformed plants, which are wellunderstood in the art, yield a plurality of transgenic plants which areharvested in a conventional manner, and a foreign protein can then beextracted from a tissue of interest or from total biomass. Proteinextraction from plant biomass can be accomplished by known methods whichare discussed, for example, by Heney and On, Anal. Biochem., 114:92-6(1981).

According to a preferred embodiment, the transgenic plant provided forcommercial production of foreign protein is a soybean plant. In anotherpreferred embodiment, the biomass of interest is seed. For therelatively small number of transgenic plants that show higher levels ofexpression, a genetic map can be generated, primarily via conventionalRFLP, PCR, and SSR analysis, which identifies the approximatechromosomal location of the integrated DNA molecule. For exemplarymethodologies in this regard, see, Glick and Thompson, Methods in PlantMolecular Biology and Biotechnology, CRC Press, Inc., Boca Raton,269:284 (1993). Map information concerning chromosomal location isuseful for proprietary protection of a subject transgenic plant.

Wang, et al. discuss “Large Scale Identification, Mapping and Genotypingof Single-Nucleotide Polymorphisms in the Human Genome,” Science,280:1077-1082 (1998), and similar capabilities are becoming increasinglyavailable for the soybean genome. Map information concerning chromosomallocation is useful for proprietary protection of a subject transgenicplant. If unauthorized propagation is undertaken and crosses made withother germplasm, the map of the integration region can be compared tosimilar maps for suspect plants to determine if the latter have a commonparentage with the subject plant. Map comparisons would involvehybridizations, RFLP, PCR, SSR, and sequencing, all of which areconventional techniques. SNPs may also be used alone or in combinationwith other techniques.

Likewise, by means of the present invention, plants can be geneticallyengineered to express various phenotypes of agronomic interest. Throughthe transformation of soybean, the expression of genes can be altered toenhance disease resistance, insect resistance, herbicide resistance,agronomic, grain quality, and other traits. Transformation can also beused to insert DNA sequences which control or help controlmale-sterility. DNA sequences native to soybean, as well as non-nativeDNA sequences, can be transformed into soybean and used to alter levelsof native or non-native proteins. Various promoters, targetingsequences, enhancing sequences, and other DNA sequences can be insertedinto the genome for the purpose of altering the expression of proteins.Reduction of the activity of specific genes (also known as genesilencing or gene suppression) is desirable for several aspects ofgenetic engineering in plants.

Many techniques for gene silencing are well known to one of skill in theart, including, but not limited to, knock-outs (such as by insertion ofa transposable element such as mu (Vicki Chandler, The Maize Handbook,Ch. 118 (Springer-Verlag 1994)) or other genetic elements such as a FRT,Lox, or other site specific integration site, antisense technology (see,e.g., Sheehy, et al., PNAS USA, 85:8805-8809 (1988); and U.S. Pat. Nos.5,107,065, 5,453,566, and 5,759,829); co-suppression (e.g., Taylor,Plant Cell, 9:1245 (1997); Jorgensen, Trends Biotech., 8(12):340-344(1990); Flavell, PNAS USA, 91:3490-3496 (1994); Finnegan, et al.,Bio/Technology, 12:883-888 (1994); Neuhuber, et al., Mol. Gen. Genet.,244:230-241 (1994)); RNA interference (Napoli, et al., Plant Cell,2:279-289 (1990); U.S. Pat. No. 5,034,323; Sharp, Genes Dev., 13:139-141(1999); Zamore, et al., Cell, 101:25-33 (2000); Montgomery, et al., PNASUSA, 95:15502-15507 (1998)), virus-induced gene silencing (Burton, etal., Plant Cell, 12:691-705 (2000); Baulcombe, Curr. Op. Plant Bio.,2:109-113 (1999)); target-RNA-specific ribozymes (Haseloff, et al.,Nature, 334: 585-591 (1988)); hairpin structures (Smith, et al., Nature,407:319-320 (2000); WO 99/53050; WO 98/53083); MicroRNA (Aukerman &Sakai, Plant Cell, 15:2730-2741 (2003)); ribozymes (Steinecke, et al.,EMBO J., 11:1525 (1992); Perriman, et al., Antisense Res. Dev., 3:253(1993)); oligonucleotide mediated targeted modification (e.g., WO03/076574 and WO 99/25853); Zn-finger targeted molecules (e.g., WO01/52620, WO 03/048345, and WO 00/42219); and other methods orcombinations of the above methods known to those of skill in the art.

Likewise, by means of the present invention, agronomic genes can beexpressed in transformed plants.

Exemplary genes implicated in this regard include, but are notlimited to, those categorized below:

DeGreef, et al.,Bio/Technology, 7:61 (1989) describe the production of transgenic plantsthat express chimeric bar genes coding for phosphinothricin acetyltransferase activity. Exemplary of genes conferring resistance tophenoxy proprionic acids and cyclohexones, such as sethoxydim andhaloxyfop are the Acc1-S1, Acc1-S2, and Acc2-S3 genes described byMarshall, et al., Theor. Appl. Genet., 83:435 (1992).

C. An herbicide that inhibits photosynthesis, such as a triazine (psbAand gs+ genes) and a benzonitrile (nitrilase gene). Przibila, et al.,Plant Cell, 3:169 (1991), describe the transformation of Chlamydomonaswith plasmids encoding mutant psbA genes. Nucleotide sequences fornitrilase genes are disclosed in U.S. Pat. No. 4,810,648 to Stalker andDNA molecules containing these genes are available under ATCC AccessionNos. 53435, 67441, and 67442.

E. Protoporphyrinogen oxidase (protox) is necessary for the productionof chlorophyll, which is necessary for all plant survival. The protoxenzyme serves as the target for a variety of herbicidal compounds. Theseherbicides also inhibit growth of all the different species of plantspresent, causing their total destruction. The development of plantscontaining altered protox activity which are resistant to theseherbicides are described in U.S. Pat.

Any of the above listed herbicide genes (A-E) can be introduced into theclaimed soybean cultivar through a variety of means including but notlimited to transformation and crossing.

3. Genes that Confer or Contribute to a Value-Added Trait, such as:

A. Modified fatty acid metabolism, for example, by transforming a plantwith an antisense gene of stearyl-ACP desaturase to increase stearicacid content of the plant. See, Knultzon, et al., Proc. Natl. Acad. Sci.USA, 89:2625 (1992).

B. Decreased phytate content: 1) Introduction of a phytase-encoding geneenhances breakdown of phytate, adding more free phosphate to thetransformed plant. For example, see, Van Hartingsveldt, et al., Gene,127:87 (1993), for a disclosure of the nucleotide sequence of anAspergillus niger phytase gene. 2) Up-regulation of a gene that reducesphytate content. In maize, this, for example, could be accomplished bycloning and then re-introducing DNA associated with one or more of thealleles, such as the LPA alleles, identified in maize mutantscharacterized by low levels of phytic acid, such as in Raboy, et al.,Maydica, 35:383 (1990), and/or by altering inositol kinase activity asin WO 02/059324, U.S. Publ. No. 2003/000901, WO 03/027243, U.S. Publ.No. 2003/0079247, WO 99/05298, U.S. Pat. No. 6,197,561, U.S. Pat. No.6,291,224, U.S. Pat. No. 6,391,348, WO 2002/059324, U.S. Publ. No.2003/0079247, WO 98/45448, W 099/55882, and WO 01/04147.

C. Modified carbohydrate composition effected, for example, bytransforming plants with a gene coding for an enzyme that alters thebranching pattern of starch, or a gene altering thioredoxin, such as NTRand/or TRX (see, U.S. Pat. No. 6,531,648, which is incorporated byreference for this purpose), and/or a gamma zein knock out or mutant,such as cs27 or TUSC27 or en27 (see, U.S. Pat. No. 6,858,778, and U.S.Publ. Nos. 2005/0160488 and 2005/0204418, which are incorporated byreference for this purpose). See, Shiroza, et al., J Bacteriol., 170:810(1988) (nucleotide sequence of Streptococcus mutans fructosyltransferasegene); Steinmetz,et al., Mol. Gen.

No. 6,232,529 (method of producing high oil seed bymodification of starch levels (AGP)). The fatty acid modification genesmentioned above may also be used to affect starch content and/orcomposition through the interrelationship of the starch and oilpathways.

D. Elevated oleic acid via FAD-2 gene modification and/or decreasedlinolenic acid via FAD-3 gene modification. See, U.S. Pat. Nos.6,063,947, 6,323,392, and International Publication WO 93/11245.Linolenic acid is one of the five most abundant fatty acids in soybeanseeds. The low oxidative stability of linolenic acid is one reason thatsoybean oil undergoes partial hydrogenation. When partiallyhydrogenated, all unsaturated fatty acids form trans fats. Soybeans arethe largest source of edible-oils in the U.S. and 40% of soybean oilproduction is partially hydrogenated. The consumption of trans fatsincreases the risk of heart disease. Regulations banning trans fats haveencouraged the development of low linolenic soybeans. Soybeanscontaining low linolenic acid percentages create a more stable oilrequiring hydrogenation less often. This provides trans fat freealternatives in products such as cooking oil.

E. Altering conjugated linolenic or linoleic acid content, such as in WO01/12800. Altering LEC1, AGP, Dek1, Superal1, milps, and various Ipagenes, such as Ipa1, Ipa3, hpt, or hggt. See, for example, WO 02/42424,WO 98/22604, WO 03/011015, WO 02/057439, WO 03/011015, U.S. Pat. Nos.6,423,886, 6,197,561, 6,825,397, 7,157,621, U.S. Publ. No. 2003/0079247,and Rivera-Madrid, R., et al., Proc. Natl. Acad. Sci., 92:5620-5624(1995).

F. Altered antioxidant content or composition, such as alteration oftocopherol or tocotrienols. See, for example, U.S. Pat. Nos. 6,787,683,7,154,029, WO 00/68393 (involving the manipulation of antioxidant levelsthrough alteration of a phytl prenyl transferase (ppt)); WO 03/082899(through alteration of a homogentisate geranyl geranyl transferase(hggt)).

G. Altered essential seed amino acids. See, for example, U.S. Pat. No.6,127,600 (method of increasing accumulation of essential amino acids inseeds); U.S. Pat.

4. Genes that Control Male Sterility:

There are several methods of conferring genetic male sterilityavailable, such as multiple mutant genes at separate locations withinthe genome that confer male sterility, as disclosed in U.S. Pat. Nos.4,654,465 and 4,727,219 to Brar, et al., and chromosomal translocationsas described by Patterson in U.S. Pat. Nos. 3,861,709 and 3,710,511. Inaddition to these methods, Albertsen, et al., U.S. Pat. No. 5,432,068,describes a system of nuclear male sterility which includes: identifyinga gene which is critical to male fertility; silencing this native genewhich is critical to male fertility; removing the native promoter fromthe essential male fertility gene and replacing it with an induciblepromoter; inserting this genetically engineered gene back into theplant; and thus creating a plant that is male sterile because theinducible promoter is not “on” resulting in the male fertility gene notbeing transcribed. Fertility is restored by inducing, or turning “on,”the promoter, which in turn allows the gene that confers male fertilityto be transcribed.

Methods for Soybean Transformation

Numerous methods for plant transformation have been developed includingbiological and physical plant transformation protocols. See, forexample, Miki, et al., “Procedures for Introducing Foreign DNA intoPlants,” in Methods in Plant Molecular Biology and Biotechnology, Glickand Thompson Eds., CRC Press, Inc., Boca Raton, pp. 67-88 (1993). Inaddition, expression vectors and in-vitro culture methods for plant cellor tissue transformation and regeneration of plants are available. See,for example, Gruber, et al., “Vectors for Plant Transformation,” inMethods in Plant Molecular Biology and Biotechnology, Glick and ThompsonEds., CRC Press, Inc., Boca Raton, pp. 89-119 (1993).

A. Agrobacterium-mediated Transformation—One method for introducing anexpression vector into plants is based on the natural transformationsystem of Agrobacterium. See, for example, Horsch, et al., Science,227:1229 (1985). A. tumefaciens and A. rhizogenes are plant pathogenicsoil bacteria which genetically transform plant cells. The Ti and Riplasmids of A. tumefaciens and A. rhizogenes, respectively, carry genesresponsible for genetic transformation of the plant. See, for example,Kado, C. I., Crit. Rev. Plant Sci., 10:1 (1991). Descriptions ofAgrobacterium vector systems and methods for Agrobacterium-mediated genetransfer are provided by Gruber, et al., supra, Miki, et al., supra, andMoloney, et al., Plant Cell Reports, 8:238 (1989). See also, U.S. Pat.No. 5,563,055 (Townsend and Thomas), issued Oct. 8, 1996.

B. Direct Gene Transfer—Several methods of plant transformation,collectively referred to as direct gene transfer, have been developed asan alternative to Agrobacterium-mediated transformation. A generallyapplicable method of plant transformation is microprojectile-mediatedtransformation where DNA is carried on the surface of microprojectilesmeasuring 1 to 4 μm. The expression vector is introduced into planttissues with a biolistic device that accelerates the microprojectiles tospeeds of 300 to 600 m/s which is sufficient to penetrate plant cellwalls and membranes. Sanford, et al., Part. Sci. Technol., 5:27 (1987);Sanford, J. C., Trends Biotech., 6:299 (1988); Klein, et al., Bio/Tech.,6:559-563 (1988); Sanford, J. C., Physiol Plant, 7:206 (1990); Klein, etal., Biotechnology, 10:268 (1992). See also, U.S. Pat. No. 5,015,580(Christou, et al.), issued May 14, 1991 and U.S. Pat. No. 5,322,783(Tomes, et al.), issued Jun. 21, 1994.

Another method for physical delivery of DNA to plants is sonication oftarget cells. Zhang, et al., Bio/Technology, 9:996 (1991).Alternatively, liposome and spheroplast fusion have been used tointroduce expression vectors into plants. Deshayes, et al., EMBO J.,4:2731 (1985); Christou, et al., Proc Natl. Acad. Sci. USA, 84:3962(1987). Direct uptake of DNA into protoplasts using CaCl₂ precipitation,polyvinyl alcohol or poly-L-ornithine have also been reported. Hain, etal., Mol. Gen. Genet., 199:161 (1985) and Draper, et al., Plant CellPhysiol., 23:451 (1982). Electroporation of protoplasts and whole cellsand tissues have also been described (Donn, et al., In Abstracts ofVIIth International Congress on Plant Cell and Tissue Culture IAPTC,A2-38, p. 53 (1990); D'Halluin, et al., Plant Cell, 4:1495-1505 (1992);and Spencer, et al., Plant Mol. Biol., 24:51-61 (1994)).

Following transformation of soybean target tissues, expression of theabove-described selectable marker genes allows for preferentialselection of transformed cells, tissues, and/or plants, usingregeneration and selection methods well known in the art.

The foregoing methods for transformation would typically be used forproducing a transgenic variety. The transgenic variety could then becrossed with another (non-transformed or transformed) variety in orderto produce a new transgenic variety. Alternatively, a genetic trait thathas been engineered into a particular soybean line using the foregoingtransformation techniques could be moved into another line usingtraditional backcrossing techniques that are well known in the plantbreeding arts. For example, a backcrossing approach could be used tomove an engineered trait from a public, non-elite variety into an elitevariety, or from a variety containing a foreign gene in its genome intoa variety or varieties that do not contain that gene. As used herein,“crossing” can refer to a simple x by y cross or the process ofbackcrossing depending on the context.

Genetic Marker Profile Through SSR and First Generation Progeny

In addition to phenotypic observations, a plant can also be identifiedby its genotype. The genotype of a plant can be characterized through agenetic marker profile which can identify plants of the same variety, ora related variety, or be used to determine or validate a pedigree.Genetic marker profiles can be obtained by techniques such asRestriction Fragment Length Polymorphisms (RFLPs), Randomly AmplifiedPolymorphic DNAs (RAPDs), Arbitrarily Primed Polymerase Chain Reaction(AP-PCR), DNA Amplification Fingerprinting (DAF), Sequence CharacterizedAmplified Regions (SCARs), Amplified Fragment Length Polymorphisms(AFLPs), Simple Sequence Repeats (SSRs) (which are also referred to asMicrosatellites), and Single Nucleotide Polymorphisms (SNPs). Forexample, see, Cregan, et al., “An Integrated Genetic Linkage Map of theSoybean Genome,” Crop Science, 39:1464-1490 (1999) and Berry, et al.,“Assessing Probability of Ancestry Using Simple Sequence RepeatProfiles: Applications to Maize Inbred Lines and Soybean Varieties,”Genetics, 165:331-342 (2003), each of which are incorporated byreference herein in their entirety.

Particular markers used for these purposes are not limited to anyparticular set of markers, but are envisioned to include any type ofmarker and marker profile which provides a means of distinguishingvarieties. One method of comparison is to use only homozygous loci forsoybean cultivar S080122.

Primers and PCR protocols for assaying these and other markers aredisclosed in the Soybase (sponsored by the USDA Agricultural ResearchService and Iowa State University). In addition to being used foridentification of soybean variety S080122, and plant parts and plantcells of soybean variety S080122, the genetic profile may be used toidentify a soybean plant produced through the use of soybean cultivarS080122 or to verify a pedigree for progeny plants produced through theuse of soybean cultivar S080122. The genetic marker profile is alsouseful in breeding and developing backcross conversions.

The present invention comprises a soybean plant characterized bymolecular and physiological data obtained from the representative sampleof said variety deposited with the American Type Culture Collection(ATCC). Further provided by the invention is a soybean plant formed bythe combination of the disclosed soybean plant or plant cell withanother soybean plant or cell and comprising the homozygous alleles ofthe variety.

Means of performing genetic marker profiles using SSR polymorphisms arewell known in the art. SSRs are genetic markers based on polymorphismsin repeated nucleotide sequences, such as microsatellites. A markersystem based on SSRs can be highly informative in linkage analysisrelative to other marker systems in that multiple alleles may bepresent. Another advantage of this type of marker is that, through useof flanking primers, detection of SSRs can be achieved, for example, bythe polymerase chain reaction (PCR), thereby eliminating the need forlabor-intensive Southern hybridization. The PCR detection is done by useof two oligonucleotide primers flanking the polymorphic segment ofrepetitive DNA. Repeated cycles of heat denaturation of the DNA followedby annealing of the primers to their complementary sequences at lowtemperatures, and extension of the annealed primers with DNA polymerase,comprise the major part of the methodology.

Following amplification, markers can be scored by electrophoresis of theamplification products. Scoring of marker genotype is based on the sizeof the amplified fragment, which may be measured by the number of basepairs of the fragment. While variation in the primer used or inlaboratory procedures can affect the reported fragment size, relativevalues should remain constant regardless of the specific primer orlaboratory used. When comparing varieties it is preferable if all SSRprofiles are performed in the same lab.

Primers used are publicly available and may be found in the Soybase orCregan supra. See also, PCT Publication No. WO 99/31964 (NucleotidePolymorphisms in Soybean); U.S. Pat. No. 6,162,967 (Positional Cloningof Soybean Cyst Nematode Resistance Genes); and U.S. application Ser.No. 09/954,773 (Soybean Sudden Death Syndrome Resistant Soybeans andMethods of Breeding and Identifying Resistant Plants), the disclosure ofwhich are incorporated herein by reference.

The SSR profile of soybean plant S080122 can be used to identify plantscomprising soybean cultivar S080122 as a parent, since such plants willcomprise the same homozygous alleles as soybean cultivar S080122.Because the soybean variety is essentially homozygous at all relevantloci, most loci should have only one type of allele present. Incontrast, a genetic marker profile of an F₁ progeny should be the sum ofthose parents, e.g., if one parent was homozygous for allele x at aparticular locus, and the other parent homozygous for allele y at thatlocus, then the F₁ progeny will be xy (heterozygous) at that locus.Subsequent generations of progeny produced by selection and breeding areexpected to be of genotype x (homozygous), y (homozygous), or xy(heterozygous) for that locus position. When the F₁ plant is selfed orsibbed for successive filial generations, the locus should be either xor y for that position.

In addition, plants and plant parts substantially benefiting from theuse of soybean cultivar S080122 in their development, such as soybeancultivar S080122 comprising a backcross conversion, transgene, orgenetic sterility factor, may be identified by having a molecular markerprofile with a high percent identity to soybean cultivar S080122. Such apercent identity might be 95%, 96%, 97%, 98%, 99%, 99.5%, or 99.9%identical to soybean cultivar S080122.

The SSR profile of soybean cultivar S080122 can also be used to identifyessentially derived varieties and other progeny varieties developed fromthe use of soybean cultivar S080122, as well as cells and other plantparts thereof. Such plants may be developed using the markers identifiedin WO 00/31964, U.S. Pat. No. 6,162,967, and U.S. application Ser. No.09/954,773. Progeny plants and plant parts produced using soybeancultivar S080122 may be identified by having a molecular marker profileof at least 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 76%,77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%,91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 99.5% geneticcontribution from soybean variety, as measured by either percentidentity or percent similarity. Such progeny may be furthercharacterized as being within a pedigree distance of soybean cultivarS080122, such as within 1, 2, 3, 4, or 5 or less cross-pollinations to asoybean plant other than soybean cultivar S080122 or a plant that hassoybean cultivar S080122 as a progenitor. Unique molecular profiles maybe identified with other molecular tools such as SNPs and RFLPs.

While determining the SSR genetic marker profile of the plants describedsupra, several unique SSR profiles may also be identified which did notappear in either parent of such plant. Such unique SSR profiles mayarise during the breeding process from recombination or mutation. Acombination of several unique alleles provides a means of identifying aplant variety, an F₁ progeny produced from such variety, and progenyproduced from such variety.

Single-Gene Conversions

When the term “soybean plant” is used in the context of the presentinvention, this also includes any single gene conversions of thatvariety. The term single gene converted plant as used herein refers tothose soybean plants which are developed by a plant breeding techniquecalled backcrossing wherein essentially all of the desired morphologicaland physiological characteristics of a variety are recovered in additionto the single gene transferred into the variety via the backcrossingtechnique. Backcrossing methods can be used with the present inventionto improve or introduce a characteristic into the variety. The term“backcrossing” as used herein refers to the repeated crossing of ahybrid progeny back to the recurrent parent, i.e., backcrossing 1, 2, 3,4, 5, 6, 7, 8, or more times to the recurrent parent. The parentalsoybean plant that contributes the gene for the desired characteristicis termed the nonrecurrent or donor parent. This terminology refers tothe fact that the nonrecurrent parent is used one time in the backcrossprotocol and therefore does not recur. The parental soybean plant towhich the gene or genes from the nonrecurrent parent are transferred isknown as the recurrent parent as it is used for several rounds in thebackcrossing protocol (Poehlman & Sleper (1994); Fehr, Principles ofCultivar Development, pp. 261-286 (1987)). In a typical backcrossprotocol, the original variety of interest (recurrent parent) is crossedto a second variety (nonrecurrent parent) that carries the single geneof interest to be transferred. The resulting progeny from this cross arethen crossed again to the recurrent parent and the process is repeateduntil a soybean plant is obtained wherein essentially all of the desiredmorphological and physiological characteristics of the recurrent parentare recovered in the converted plant, in addition to the singletransferred gene from the nonrecurrent parent.

The selection of a suitable recurrent parent is an important step for asuccessful backcrossing procedure. The goal of a backcross protocol isto alter or substitute a single trait or characteristic in the originalvariety. To accomplish this, a single gene of the recurrent variety ismodified or substituted with the desired gene from the nonrecurrentparent, while retaining essentially all of the rest of the desiredgenetic, and therefore the desired physiological and morphologicalconstitution of the original variety. The choice of the particularnonrecurrent parent will depend on the purpose of the backcross; one ofthe major purposes is to add some agronomically important trait to theplant. The exact backcrossing protocol will depend on the characteristicor trait being altered to determine an appropriate testing protocol.Although backcrossing methods are simplified when the characteristicbeing transferred is a dominant allele, a recessive allele may also betransferred. In this instance it may be necessary to introduce a test ofthe progeny to determine if the desired characteristic has beensuccessfully transferred.

Many single gene traits have been identified that are not regularlyselected for in the development of a new variety but that can beimproved by backcrossing techniques. Single gene traits may or may notbe transgenic. Examples of these traits include, but are not limited to,male sterility, waxy starch, herbicide resistance, resistance forbacterial, fungal, or viral disease, insect resistance, male fertility,enhanced nutritional quality, industrial usage, yield stability, andyield enhancement. These genes are generally inherited through thenucleus. Several of these single gene traits are described in U.S. Pat.Nos. 5,959,185, 5,973,234, and 5,977,445, the disclosures of which arespecifically hereby incorporated by reference.

Introduction of a New Trait or Locus into Soybean Cultivar S080122

Variety S080122 represents a new base genetic variety into which a newlocus or trait may be introgressed. Direct transformation andbackcrossing represent two important methods that can be used toaccomplish such an introgression. The term backcross conversion andsingle locus conversion are used interchangeably to designate theproduct of a backcrossing program.

Backcross Conversions of Soybean Cultivar S080122

A backcross conversion of soybean cultivar S080122 occurs when DNAsequences are introduced through backcrossing (Hallauer, et al., “CornBreeding,” Corn and Corn Improvements, No. 18, pp. 463-481 (1988)), withsoybean cultivar S080122 utilized as the recurrent parent. Bothnaturally occurring and transgenic DNA sequences may be introducedthrough backcrossing techniques. A backcross conversion may produce aplant with a trait or locus conversion in at least two or morebackcrosses, including at least 2 crosses, at least 3 crosses, at least4 crosses, at least 5 crosses, and the like. Molecular marker assistedbreeding or selection may be utilized to reduce the number ofbackcrosses necessary to achieve the backcross conversion. For example,see, Openshaw, S.J., et al., Marker-assisted Selection in BackcrossBreeding, Proceedings Symposium of the Analysis of Molecular Data, CropScience Society of America, Corvallis, Oreg. (August 1994), where it isdemonstrated that a backcross conversion can be made in as few as twobackcrosses.

The complexity of the backcross conversion method depends on the type oftrait being transferred (single genes or closely linked genes ascompared to unlinked genes), the level of expression of the trait, thetype of inheritance (cytoplasmic or nuclear), and the types of parentsincluded in the cross. It is understood by those of ordinary skill inthe art that for single gene traits that are relatively easy toclassify, the backcross method is effective and relatively easy tomanage. (See, Hallauer, et al., Corn and Corn Improvement, Sprague andDudley, Third Ed. (1998)). Desired traits that may be transferredthrough backcross conversion include, but are not limited to, sterility(nuclear and cytoplasmic), fertility restoration, nutritionalenhancements, drought tolerance, nitrogen utilization, altered fattyacid profile, low phytate, industrial enhancements, disease resistance(bacterial, fungal, or viral), insect resistance, and herbicideresistance. In addition, an introgression site itself, such as an FRTsite, Lox site, or other site specific integration site, may be insertedby backcrossing and utilized for direct insertion of one or more genesof interest into a specific plant variety. In some embodiments of theinvention, the number of loci that may be backcrossed into soybeancultivar S080122 is at least 1, 2, 3, 4, or 5, and/or no more than 6, 5,4, 3, or 2. A single locus may contain several transgenes, such as atransgene for disease resistance that, in the same expression vector,also contains a transgene for herbicide resistance. The gene forherbicide resistance may be used as a selectable marker and/or as aphenotypic trait. A single locus conversion of site specific integrationsystem allows for the integration of multiple genes at the convertedloci.

The backcross conversion may result from either the transfer of adominant allele or a recessive allele. Selection of progeny containingthe trait of interest is accomplished by direct selection for a traitassociated with a dominant allele. Transgenes transferred viabackcrossing typically function as a dominant single gene trait and arerelatively easy to classify. Selection of progeny for a trait that istransferred via a recessive allele requires growing and selfing thefirst backcross generation to determine which plants carry the recessivealleles. Recessive traits may require additional progeny testing insuccessive backcross generations to determine the presence of the locusof interest. The last backcross generation is usually selfed to givepure breeding progeny for the gene(s) being transferred, although abackcross conversion with a stably introgressed trait may also bemaintained by further backcrossing to the recurrent parent withselection for the converted trait.

Along with selection for the trait of interest, progeny are selected forthe phenotype of the recurrent parent. The backcross is a form ofinbreeding, and the features of the recurrent parent are automaticallyrecovered after successive backcrosses. Poehlman, Breeding Field Crops,p. 204 (1987). Poehlman suggests from one to four or more backcrosses,but as noted above, the number of backcrosses necessary can be reducedwith the use of molecular markers. Other factors, such as a geneticallysimilar donor parent, may also reduce the number of backcrossesnecessary. As noted by Poehlman, backcrossing is easiest for simplyinherited, dominant, and easily recognized traits.

One process for adding or modifying a trait or locus in soybean varietyS080122 comprises crossing soybean cultivar S080122 plants grown fromsoybean cultivar S080122 seed with plants of another soybean varietythat comprise the desired trait or locus, selecting F₁ progeny plantsthat comprise the desired trait or locus to produce selected F₁ progenyplants, crossing the selected progeny plants with the soybean cultivarS080122 plants to produce backcross progeny plants, selecting forbackcross progeny plants that have the desired trait or locus and themorphological characteristics of soybean variety S080122 to produceselected backcross progeny plants, and backcrossing to soybean cultivarS080122 three or more times in succession to produce selected fourth orhigher backcross progeny plants that comprise said trait or locus. Themodified soybean cultivar S080122 may be further characterized as havingthe physiological and morphological characteristics of soybean varietyS080122 listed in Table 1 as determined at the 5% significance levelwhen grown in the same environmental conditions and/or may becharacterized by percent similarity or identity to soybean cultivarS080122 as determined by SSR markers. The above method may be utilizedwith fewer backcrosses in appropriate situations, such as when the donorparent is highly related or markers are used in the selection step.Desired traits that may be used include those nucleic acids known in theart, some of which are listed herein, that will affect traits throughnucleic acid expression or inhibition. Desired loci include theintrogression of FRT, Lox, and other sites for site specificintegration, which may also affect a desired trait if a functionalnucleic acid is inserted at the integration site.

In addition, the above process and other similar processes describedherein may be used to produce first generation progeny soybean seed byadding a step at the end of the process that comprises crossing soybeancultivar S080122 with the introgressed trait or locus with a differentsoybean plant and harvesting the resultant first generation progenysoybean seed.

Tissue Culture

Further reproduction of the variety can occur by tissue culture andregeneration. Tissue culture of various tissues of soybeans andregeneration of plants therefrom is well known and widely published. Forexample, reference may be had to Komatsuda, T., et al., Crop Sci.,31:333-337 (1991); Stephens, P. A., et al., Theor. Appl. Genet.,82:633-635 (1991); Komatsuda, T., et al., Plant Cell, Tissue and OrganCulture, 28:103-113 (1992); Dhir, S., et al., Plant Cell Reports,11:285-289 (1992); Pandey, P., et al., Japan J. Breed., 42:1-5 (1992);and Shetty, K., et al., Plant Science, 81:245-251 (1992); as well asU.S. Pat. No. 5,024,944, issued Jun. 18, 1991 to Collins, et al. andU.S. Pat. No. 5,008,200, issued Apr. 16, 1991 to Ranch, et al. Thus,another aspect of this invention is to provide cells which upon growthand differentiation produce soybean plants having the physiological andmorphological characteristics of soybean cultivar S080122.

As used herein, the term “tissue culture” indicates a compositioncomprising isolated cells of the same or a different type or acollection of such cells organized into parts of a plant. Exemplarytypes of tissue cultures are protoplasts, calli, plant clumps, and plantcells that can generate tissue culture that are intact in plants orparts of plants, such as embryos, pollen, flowers, seeds, pods,petioles, leaves, stems, roots, root tips, anthers, pistils, and thelike. Means for preparing and maintaining plant tissue culture are wellknown in the art. By way of example, a tissue culture comprising organshas been used to produce regenerated plants. U.S. Pat. Nos. 5,959,185,5,973,234, and 5,977,445 describe certain techniques, the disclosures ofwhich are incorporated herein by reference.

Using Soybean Cultivar S080122 to Develop other Soybean Varieties

Soybean varieties such as soybean cultivar S080122 are typicallydeveloped for use in seed and grain production. However, soybeanvarieties such as soybean cultivar S080122 also provide a source ofbreeding material that may be used to develop new soybean varieties.Plant breeding techniques known in the art and used in a soybean plantbreeding program include, but are not limited to, recurrent selection,mass selection, bulk selection, mass selection, backcrossing, pedigreebreeding, open pollination breeding, restriction fragment lengthpolymorphism enhanced selection, genetic marker enhanced selection,making double haploids, and transformation. Often combinations of thesetechniques are used. The development of soybean varieties in a plantbreeding program requires, in general, the development and evaluation ofhomozygous varieties. There are many analytical methods available toevaluate a new variety. The oldest and most traditional method ofanalysis is the observation of phenotypic traits, but genotypic analysismay also be used.

Additional Breeding Methods

This invention is directed to methods for producing a soybean plant bycrossing a first parent soybean plant with a second parent soybean plantwherein either the first or second parent soybean plant is varietyS080122. The other parent may be any other soybean plant, such as asoybean plant that is part of a synthetic or natural population. Anysuch methods using soybean variety S080122 are part of this invention:selfing, sibbing, backcrosses, mass selection, pedigree breeding, bulkselection, hybrid production, crosses to populations, and the like.These methods are well known in the art and some of the more commonlyused breeding methods are described below. Descriptions of breedingmethods can be found in one of several reference books (e.g., Allard,Principles of Plant Breeding (1960); Simmonds, Principles of CropImprovement (1979); Sneep, et al. (1979); Fehr, “Breeding Methods forCultivar Development,” Chapter 7, Soybean Improvement, Production andUses, 2.sup.nd ed., Wilcox editor (1987)).

The following describes breeding methods that may be used with soybeancultivar S080122 in the development of further soybean plants. One suchembodiment is a method for developing a cultivar S080122 progeny soybeanplant in a soybean plant breeding program comprising: obtaining thesoybean plant, or a part thereof, of cultivar S080122, utilizing saidplant, or plant part, as a source of breeding material, and selecting asoybean cultivar S080122 progeny plant with molecular markers in commonwith cultivar S080122 and/or with morphological and/or physiologicalcharacteristics selected from the characteristics listed in Tables 1 or2. Breeding steps that may be used in the soybean plant breeding programinclude pedigree breeding, backcrossing, mutation breeding, andrecurrent selection. In conjunction with these steps, techniques such asRFLP-enhanced selection, genetic marker enhanced selection (for example,SSR markers), and the making of double haploids may be utilized.

Another method involves producing a population of soybean cultivarS080122 progeny soybean plants, comprising crossing cultivar S080122with another soybean plant, thereby producing a population of soybeanplants which, on average, derive 50% of their alleles from soybeancultivar S080122. A plant of this population may be selected andrepeatedly selfed or sibbed with a soybean cultivar resulting from thesesuccessive filial generations. One embodiment of this invention is thesoybean cultivar produced by this method and that has obtained at least50% of its alleles from soybean cultivar S080122.

One of ordinary skill in the art of plant breeding would know how toevaluate the traits of two plant varieties to determine if there is nosignificant difference between the two traits expressed by thosevarieties. For example, see, Fehr and Walt, Principles of CultivarDevelopment, pp. 261-286 (1987). Thus the invention includes soybeancultivar S080122 progeny soybean plants comprising a combination of atleast two cultivar S080122 traits selected from the group consisting ofthose listed in Tables 1 and 2 or the cultivar S080122 combination oftraits listed in the Summary of the Invention, so that said progenysoybean plant is not significantly different for said traits thansoybean cultivar S080122 as determined at the 5% significance level whengrown in the same environmental conditions. Using techniques describedherein, molecular markers may be used to identify said progeny plant asa soybean cultivar S080122 progeny plant. Mean trait values may be usedto determine whether trait differences are significant, and preferablythe traits are measured on plants grown under the same environmentalconditions. Once such a variety is developed, its value is substantialsince it is important to advance the germplasm base as a whole in orderto maintain or improve traits such as yield, disease resistance, pestresistance, and plant performance in extreme environmental conditions.

Progeny of soybean cultivar S080122 may also be characterized throughtheir filial relationship with soybean cultivar S080122, as for example,being within a certain number of breeding crosses of soybean cultivarS080122. A breeding cross is a cross made to introduce new genetics intothe progeny, and is distinguished from a cross, such as a self or a sibcross, made to select among existing genetic alleles. The lower thenumber of breeding crosses in the pedigree, the closer the relationshipbetween soybean cultivar S080122 and its progeny. For example, progenyproduced by the methods described herein may be within 1, 2, 3, 4, or 5breeding crosses of soybean cultivar S080122.

As used herein, the term “plant” includes plant cells, plantprotoplasts, plant cell tissue cultures from which soybean plants can beregenerated, plant calli, plant clumps, and plant cells that are intactin plants or parts of plants, such as embryos, pollen, ovules, flowers,pods, leaves, roots, root tips, anthers, cotyledons, hypocotyls,meristematic cells, stems, pistils, petiole, and the like.

Pedigree Breeding

Pedigree breeding starts with the crossing of two genotypes, such assoybean cultivar S080122 and another soybean variety having one or moredesirable characteristics that is lacking or which complements soybeancultivar S080122. If the two original parents do not provide all thedesired characteristics, other sources can be included in the breedingpopulation. In the pedigree method, superior plants are selfed andselected in successive filial generations. In the succeeding filialgenerations, the heterozygous condition gives way to homogeneousvarieties as a result of self-pollination and selection. Typically inthe pedigree method of breeding, five or more successive filialgenerations of selfing and selection is practiced: F₁ to F₂; F₂ to F₃;F₃ to F₄; F₄ to F₅; etc. After a sufficient amount of inbreeding,successive filial generations will serve to increase seed of thedeveloped variety. Preferably, the developed variety compriseshomozygous alleles at about 95% or more of its loci.

In addition to being used to create a backcross conversion, backcrossingcan also be used in combination with pedigree breeding. As discussedpreviously, backcrossing can be used to transfer one or morespecifically desirable traits from one variety, the donor parent, to adeveloped variety called the recurrent parent, which has overall goodagronomic characteristics yet lacks that desirable trait or traits.However, the same procedure can be used to move the progeny toward thegenotype of the recurrent parent, but at the same time retain manycomponents of the nonrecurrent parent by stopping the backcrossing at anearly stage and proceeding with selfing and selection. For example, asoybean variety may be crossed with another variety to produce a firstgeneration progeny plant. The first generation progeny plant may then bebackcrossed to one of its parent varieties to create a BC₁ or BC₂.Progeny are selfed and selected so that the newly developed variety hasmany of the attributes of the recurrent parent and yet several of thedesired attributes of the nonrecurrent parent. This approach leveragesthe value and strengths of the recurrent parent for use in new soybeanvarieties.

Therefore, an embodiment of this invention is a method of making abackcross conversion of soybean variety S080122, comprising the steps ofcrossing a plant of soybean variety S080122 with a donor plantcomprising a desired trait, selecting an F₁ progeny plant comprising thedesired trait, and backcrossing the selected F₁ progeny plant to a plantof soybean variety S080122. This method may further comprise the step ofobtaining a molecular marker profile of soybean variety S080122 andusing the molecular marker profile to select for a progeny plant withthe desired trait and the molecular marker profile of soybean cultivarS080122. In one embodiment, the desired trait is a mutant gene ortransgene present in the donor parent.

Recurrent Selection and Mass Selection

Recurrent selection is a method used in a plant breeding program toimprove a population of plants. Soybean cultivar S080122 is suitable foruse in a recurrent selection program. The method entails individualplants cross pollinating with each other to form progeny. The progenyare grown and the superior progeny selected by any number of selectionmethods, which include individual plant, half-sib progeny, full-sibprogeny, and selfed progeny. The selected progeny are cross pollinatedwith each other to form progeny for another population. This populationis planted and again superior plants are selected to cross pollinatewith each other. Recurrent selection is a cyclical process and thereforecan be repeated as many times as desired. The objective of recurrentselection is to improve the traits of a population. The improvedpopulation can then be used as a source of breeding material to obtainnew varieties for commercial or breeding use, including the productionof a synthetic cultivar. A synthetic cultivar is the resultant progenyformed by the intercrossing of several selected varieties.

Mass selection is a useful technique when used in conjunction withmolecular marker enhanced selection. In mass selection, seeds fromindividuals are selected based on phenotype or genotype. These selectedseeds are then bulked and used to grow the next generation. Bulkselection requires growing a population of plants in a bulk plot,allowing the plants to self-pollinate, harvesting the seed in bulk, andthen using a sample of the seed harvested in bulk to plant the nextgeneration. Also, instead of self pollination, directed pollinationcould be used as part of the breeding program.

Mutation Breeding

Mutation breeding is another method of introducing new traits intosoybean variety S080122. Mutations that occur spontaneously or areartificially induced can be useful sources of variability for a plantbreeder. The goal of artificial mutagenesis is to increase the rate ofmutation for a desired characteristic. Mutation rates can be increasedby many different means including temperature, long-term seed storage,tissue culture conditions, radiation; such as X-rays, Gamma rays (e.g.,cobalt 60 or cesium 137), neutrons, (product of nuclear fission byuranium 235 in an atomic reactor), Beta radiation (emitted fromradioisotopes such as phosphorus 32 or carbon 14), or ultravioletradiation (preferably from 2500 to 2900 nm), or chemical mutagens (suchas base analogues (5-bromo-uracil)), related compounds (8-ethoxycaffeine), antibiotics (streptonigrin), alkylating agents (sulfurmustards, nitrogen mustards, epoxides, ethylenamines, sulfates,sulfonates, sulfones, lactones), azide, hydroxylamine, nitrous acid, oracridines. Once a desired trait is observed through mutagenesis thetrait may then be incorporated into existing germplasm by traditionalbreeding techniques. Details of mutation breeding can be found in Fehr,“Principles of Cultivar Development,” Macmillan Publishing Company(1993). In addition, mutations created in other soybean plants may beused to produce a backcross conversion of soybean cultivar S080122 thatcomprises such mutation.

Breeding with Molecular Markers

Molecular markers, which includes markers identified through the use oftechniques such as Isozyme Electrophoresis, Restriction Fragment LengthPolymorphisms (RFLPs), Randomly Amplified Polymorphic DNAs (RAPDs),Arbitrarily Primed Polymerase Chain Reaction (AP-PCR), DNA AmplificationFingerprinting (DAF), Sequence Characterized Amplified Regions (SCARs),Amplified Fragment Length Polymorphisms (AFLPs), Simple Sequence Repeats(SSRs), and Single Nucleotide Polymorphisms (SNPs), may be used in plantbreeding methods utilizing soybean cultivar S080122.

Isozyme Electrophoresis and RFLPs have been widely used to determinegenetic composition. Shoemaker and Olsen, Molecular Linkage Map ofSoybean (Glycine max L. Merr.), pp. 6.131-6.138 (1993). In S. J. O'Brien(ed.), Genetic Maps: Locus Maps of Complex Genomes, Cold Spring HarborLaboratory Press, Cold Spring Harbor, N.Y., developed a moleculargenetic linkage map that consisted of 25 linkage groups with about 365RFLP, 11 RAPD (random amplified polymorphic DNA), 3 classical markers,and 4 isozyme loci. See also, Shoemaker, R. C., 1994 RFLP Map ofSoybean, pp. 299-309; In R. L. Phillips and I. K. Vasil (ed.), DNA-basedmarkers in plants, Kluwer Academic Press Dordrecht, the Netherlands.

SSR technology is currently the most efficient and practical markertechnology. More marker loci can be routinely used, and more alleles permarker locus can be found, using SSRs in comparison to RFLPs. Forexample, Diwan and Cregan described a highly polymorphic microsatelliteloci in soybean with as many as 26 alleles. (Diwan, N., and Cregan. P.B., Automated sizing of fluorescent-labeled simple sequence repeat (SSR)markers to assay genetic variation in Soybean, Theor. Appl. Genet.,95:220-225 (1997). Single Nucleotide Polymorphisms may also be used toidentify the unique genetic composition of the invention and progenyvarieties retaining that unique genetic composition. Various molecularmarker techniques may be used in combination to enhance overallresolution.

Soybean DNA molecular marker linkage maps have been rapidly constructedand widely implemented in genetic studies. One such study is describedin Cregan, et. al, “An Integrated Genetic Linkage Map of the SoybeanGenome,” Crop Science, 39:1464-1490 (1999). Sequences and PCR conditionsof SSR Loci in Soybean, as well as the most current genetic map, may befound in Soybase on the World Wide Web.

One use of molecular markers is Quantitative Trait Loci (QTL) mapping.QTL mapping is the use of markers, which are known to be closely linkedto alleles that have measurable effects on a quantitative trait.Selection in the breeding process is based upon the accumulation ofmarkers linked to the positive effecting alleles and/or the eliminationof the markers linked to the negative effecting alleles from the plant'sgenome.

Molecular markers can also be used during the breeding process for theselection of qualitative traits. For example, markers closely linked toalleles or markers containing sequences within the actual alleles ofinterest can be used to select plants that contain the alleles ofinterest during a backcrossing breeding program. The markers can also beused to select for the genome of the recurrent parent and against thegenome of the donor parent. Using this procedure can minimize the amountof genome from the donor parent that remains in the selected plants. Itcan also be used to reduce the number of crosses back to the recurrentparent needed in a backcrossing program. The use of molecular markers inthe selection process is often called genetic marker enhanced selection.Molecular markers may also be used to identify and exclude certainsources of germplasm as parental varieties or ancestors of a plant byproviding a means of tracking genetic profiles through crosses.

Production of Double Haploids

The production of double haploids can also be used for the developmentof plants with a homozygous phenotype in the breeding program. Forexample, a soybean plant for which soybean cultivar S080122 is a parentcan be used to produce double haploid plants. Double haploids areproduced by the doubling of a set of chromosomes (1 N) from aheterozygous plant to produce a completely homozygous individual. Forexample, see, Wan, et al., “Efficient Production of Doubled HaploidPlants Through Colchicine Treatment of Anther-Derived Maize Callus,”Theoretical and Applied Genetics, 77:889-892 (1989) and U.S. Pat. No.7,135,615. This can be advantageous because the process omits thegenerations of selfing needed to obtain a homozygous plant from aheterozygous source.

Haploid induction systems have been developed for various plants toproduce haploid tissues, plants and seeds. The haploid induction systemcan produce haploid plants from any genotype by crossing a selected line(as female) with an inducer line. Such inducer lines for maize includeStock 6 (Coe, Am. Nat., 93:381-382 (1959); Sharkar and Coe, Genetics,54:453-464 (1966); KEMS (Deimling, Roeber, and Geiger, Vortr.Pflanzenzuchtg, 38:203-224 (1997); or KMS and ZMS (Chalyk, Bylich &Chebotar, MNL, 68:47 (1994); Chalyk & Chebotar, Plant Breeding,119:363-364 (2000)); and indeterminate gametophyte (ig) mutation(Kermicle, Science, 166:1422-1424 (1969). The disclosures of which areincorporated herein by reference.

Methods for obtaining haploid plants are also disclosed in Kobayashi,M., et al., Journ. of Heredity, 71(1):9-14 (1980); Pollacsek, M.,Agronomie (Paris) 12(3):247-251 (1992); Cho-Un-Haing, et al., Journ. ofPlant Biol., 39(3):185-188 (1996); Verdoodt, L., et al., 96(2):294-300(February 1998); Genetic Manipulation in Plant Breeding, ProceedingsInternational Symposium Organized by EUCARPIA, Berlin, Germany (Sept.8-13,1985); Chalyk, et al., Maize Genet Coop., Newsletter 68:47 (1994).

Thus, an embodiment of this invention is a process for making asubstantially homozygous soybean cultivar S080122 progeny plant byproducing or obtaining a seed from the cross of soybean cultivar S080122and another soybean plant and applying double haploid methods to the F₁seed or F₁ plant or to any successive filial generation. Based onstudies in maize and currently being conducted in soybean, such methodswould decrease the number of generations required to produce a varietywith similar genetics or characteristics to soybean cultivar S080122.See, Bernardo, R. and Kahler, A. L., Theor. Appl. Genet., 102:986-992(2001).

In particular, a process of making seed retaining the molecular markerprofile of soybean variety S080122 is contemplated, such processcomprising obtaining or producing F₁ seed for which soybean varietyS080122 is a parent, inducing doubled haploids to create progeny withoutthe occurrence of meiotic segregation, obtaining the molecular markerprofile of soybean variety S080122, and selecting progeny that retainthe molecular marker profile of soybean cultivar S080122.

Descriptions of other breeding methods that are commonly used fordifferent traits and crops can be found in one of several referencebooks (e.g., Allard (1960); Simmonds (1979); Sneep, et al. (1979); Fehr(1987)).

INDUSTRIAL USES

The seed of soybean cultivar S080122, the plant produced from the seed,the hybrid soybean plant produced from the crossing of the variety withany other soybean plant, hybrid seed, and various parts of the hybridsoybean plant can be utilized for human food, livestock feed, and as araw material in industry. The soybean seeds produced by soybean cultivarS080122 can be crushed, or a component of the soybean seeds can beextracted, in order to comprise a commodity plant product, such asprotein concentrate, protein isolate, soybean hulls, meal, flour, or oilfor a food or feed product.

The soybean is the world's leading source of vegetable oil and proteinmeal. The oil extracted from soybeans is used for cooking oil,margarine, and salad dressings. Soybean oil is composed of saturated,monounsaturated, and polyunsaturated fatty acids. It has a typicalcomposition of 11% palmitic, 4% stearic, 25% oleic, 50% linoleic, and 9%linolenic fatty acid content (“Economic Implications of Modified SoybeanTraits Summary Report,” Iowa Soybean Promotion Board and AmericanSoybean Association Special Report 92S (May 1990)). Changes in fattyacid composition for improved oxidative stability and nutrition areconstantly sought after. Industrial uses of soybean oil, which issubjected to further processing, include ingredients for paints,plastics, fibers, detergents, cosmetics, lubricants, and biodiesel fuel.Soybean oil may be split, inter-esterified, sulfurized, epoxidized,polymerized, ethoxylated, or cleaved. Designing and producing soybeanoil derivatives with improved functionality and improved oliochemistryis a rapidly growing field. The typical mixture of triglycerides isusually split and separated into pure fatty acids, which are thencombined with petroleum-derived alcohols or acids, nitrogen, sulfonates,chlorine, or with fatty alcohols derived from fats and oils to producethe desired type of oil or fat.

Soybean cultivar S080122 can be used to produce soybean oil. To producesoybean oil, the soybeans harvested from soybean cultivar S080122 arecracked, adjusted for moisture content, rolled into flakes and the oilis solvent-extracted from the flakes with commercial hexane. The oil isthen refined, blended for different applications, and sometimeshydrogenated. Soybean oils, both liquid and partially hydrogenated, areused domestically and exported, sold as “vegetable oil” or are used in awide variety of processed foods.

Soybeans are also used as a food source for both animals and humans.Soybeans are widely used as a source of protein for poultry, swine, andcattle feed. During processing of whole soybeans, the fibrous hull isremoved and the oil is extracted. The remaining soybean meal is acombination of carbohydrates and approximately 50% protein.

Soybean cultivar S080122 can be used to produce meal. After oil isextracted from whole soybeans harvested from soybean cultivar S080122,the remaining material or “meal” is “toasted” (a misnomer because theheat treatment is with moist steam) and ground in a hammer mill. Soybeanmeal is an essential element of the American production method ofgrowing farm animals, such as poultry and swine, on an industrial scalethat began in the 1930s; and more recently the aquaculture of catfish.Ninety-eight percent of the U.S. soybean crop is used for livestockfeed. Soybean meal is also used in lower end dog foods. Soybean mealproduced from soybean cultivar S080122 can also be used to producesoybean protein concentrate and soybean protein isolate.

In addition to soybean meal, soybean cultivar S080122 can be used toproduce soy flour. Soy flour refers to defatted soybeans where specialcare was taken during desolventizing (not toasted) to minimizedenaturation of the protein and to retain a high Nitrogen SolubilityIndex (NSI) in making the flour. Soy flour is the starting material forproduction of soy concentrate and soy protein isolate. Defatted soyflour is obtained from solvent extracted flakes, and contains less than1% oil. Full-fat soy flour is made from unextracted, dehulled beans, andcontains about 18% to 20% oil. Due to its high oil content, aspecialized Alpine Fine Impact Mill must be used for grinding ratherthan the more common hammer mill. Low-fat soy flour is made by addingback some oil to defatted soy flour. The lipid content varies accordingto specifications, usually between 4.5% and 9%. High-fat soy flour canalso be produced by adding back soybean oil to defatted flour at thelevel of 15%. Lecithinated soy flour is made by adding soybean lecithinto defatted, low-fat or high-fat soy flours to increase theirdispersibility and impart emulsifying properties. The lecithin contentvaries up to 15%.

For human consumption, soybean cultivar S080122 can be used to produceedible protein ingredients which offer a healthier, less expensivereplacement for animal protein in meats, as well as in dairy-typeproducts. The soybeans produced by soybean cultivar S080122 can beprocessed to produce a texture and appearance similar to many otherfoods. For example, soybeans are the primary ingredient in many dairyproduct substitutes (e.g., soy milk, margarine, soy ice cream, soyyogurt, soy cheese, and soy cream cheese) and meat substitutes (e.g.,veggie burgers). These substitutes are readily available in mostsupermarkets. Although soy milk does not naturally contain significantamounts of digestible calcium (the high calcium content of soybeans isbound to the insoluble constituents and remains in the soy pulp), manymanufacturers of soy milk sell calcium-enriched products as well. Soy isalso used in tempeh: the beans (sometimes mixed with grain) arefermented into a solid cake.

Additionally, soybean cultivar S080122 can be used to produce varioustypes of “fillers” in meat and poultry products. Food service, retail,and institutional (primarily school lunch and correctional) facilitiesregularly use such “extended” products, that is, products which containsoy fillers. Extension may result in diminished flavor, but fat andcholesterol are reduced by adding soy fillers to certain products.Vitamin and mineral fortification can be used to make soy productsnutritionally equivalent to animal protein; the protein quality isalready roughly equivalent.
